    Default What Stone Is This?

    Anybody have any ideas? I suspect it is a form of coticule from what it looks and behaves like.

    Dimensions are 6.25" x 1" x 1.6" roughly, widest part is not ground smooth but seems fractured somehow to shape. Sides are circular ground to be pretty flat and smooth.

    Are you sure it is a hone? Looks like a brick to me.

    Not sure, but I believe it is a natural stone. I bought it real cheap at an estate sale down the street, nobody there could tell me what it was but figured I'd take a chance on it.
    Are you referring to the roughness of the unsurface ground sides?

    It appears to be a mottled piece of Vermont slate. It could have been a hone or building material, but either way it is well worth testing. Lap it and test. In my experience, best not to use water. Use glycerin and water mix, oil, or lather. A good piece can make an edge ultra keen but a touch live/hot

    Actually it kind of looks like limestone.

    If you had a little dilute HCl a dropper full would fizz if that were the case.

    I have no HCl to test with, can you make it easily?

    What would I lap it with assuming it is Vermont slate? I have an Atoms 140 and DMT Diafold from xxc to of. Would any of these be a good choice?

    Pretty much anything you have would be fine, they aren't brutally hard and are compliant to lap.
